CBSE Sample Paper 2021, Deleted Chapters For Class 12 Physics Exam
Students appearing for the upcoming CBSE Class 12 final exams this year must go through the deleted syllabus of Physics Class 12 CBSE 2020-21 to have an idea of the new exam pattern.
The Central Board of Secondary Education (CBSE) has reduced the Class 12 syllabus by 30 per cent to compensate for the loss of studies due to the ongoing COVID-19 pandemic. The CBSE Class 12 reduced syllabus for all the subjects are available on the official CBSE websites -- cbse.nic.in and cbseacademic.nic.in. The exam conducting body has reduced the syllabus after considering the challenges faced by the students during the coronavirus situation. The CBSE Class 12 exams will be held from May 4, 2021.

The deleted portion of Class 12 CBSE, however, will be applicable only for the upcoming 2021 board exam. Students can check the CBSE reduced syllabus and prepare for their exams accordingly so that they do not waste time studying extra. The CBSE syllabus 2021 has been rationalised to the extent possible by keeping the core concepts.

In case of Practicals, the CBSE Class 12 deleted syllabus Physics also mentions that no investigatory project and activity will be required to be demonstrated and eight experiments in place of 12 will be required. The eight CBSE Class 12 Physics experiments will be clubbed on the basis of skills.
The board has also released the CBSE Class 12 Physics sample papers along with their marking schemes. The CBSE Class 12 Physics sample papers contain all the questions asked in the previous years and the associated marking scheme. With the help of CBSE Class 12 Physics sample papers, students taking the CBSE 2021 Class 12 exams can check the type of questions asked and the weightage of questions from each unit in the previous years.
